Patient information software system including infusion map

ABSTRACT

An infusion map system includes a memory storing at least infusion mapping instructions, and a processor that executes the stored instructions. When the processor executes the infusion mapping instructions, the infusion map system performs a displaying function that displays at least a portion of an electronic medical record associated with a patient and a diagramming function that receives the electronic medical record and generates an infusion map showing all intravenous drugs being administered to the patient. For each of the drugs, the infusion map further illustrates a route of administration for the drug. An order administering function performed by the system allows a user to alter the infusion map, and a record updating function of annotating the electronic medical record to correspond to the altered infusion map.

RELATED APPLICATIONS

The present application is a Continuation application of U.S. patentapplication Ser. No. 14/020,483 filed Sep. 6, 2013, which claims 35 USC119 priority from U.S. Patent Application Ser. No. 61/697,648, filedSep. 6, 2012, which is incorporated by reference.

FIELD OF THE INVENTION

This invention relates to patient information software, and moreparticularly to software for displaying a patient-specific, interactive,real-time infusion system map.

BACKGROUND

Currently, medication delivery systems are limited due to the number ofparties involved in medicating a hospitalized patient, and a lack ofcomplete, consistent information provided to all parties. Typically,physicians write prescriptions for patients. Pharmacists fill anddispense the prescriptions without knowledge of the patient's infusionsetup (route of administration of the various drugs prescribed is oftenunspecified or underspecified). Nurses are responsible for administeringthe prescribed drugs according to instructions from both the physiciansand pharmacists. This leads to nurses making critical decisions aboutinfusion setup and drug administration, which can lead to errors. Inparticular, the above workflow can, among other things, lead tounnoticed drug incompatibilities, inadvertent bolus, excessive lag time,and errors in the “five rights” of drug administration (ensuring theright patient, right drug, right dose, right time, and rightadministration route).

Pharmacists lack the ability to see the physical infusion system ascreated by the administering nurses. Accordingly, the pharmacists relyon the patient's medical record when checking and filling prescriptions.Nurses manually map, label, and trace the various infusion lines. Thenurse also manually selects a route, port, and catheter hub for anewly-added drug deliverable by infusion, and manually records thisinformation in the patient's medical administration record (MAR).Typically, a single nurse is responsible for many patients throughout ashift, and is constantly receiving, discharging, and transferringpatients. Accordingly, medical records may lack the specificity requiredfor a pharmacist to fully verify that there are no undesired druginteractions.

Accordingly, there is a need to provide a system for health careprofessionals to view an accurate representation of a patient's infusionmap in real time. Likewise, there is a need to provide a system thataids clinicians in accurately recording the patient's infusion map inhis or her medical record. Likewise, there is a need to provide a systemthat models infusion setups to aid decision making and execution byclinicians to reduce medication errors and save time.

SUMMARY

A patient information software system with infusion map addresses theseneeds. The system provides an accurate and up-to-date representation ofeach patient's infusion map, and allows clinicians to easily modify thepresented map. The system further updates the patient's electronicmedical record to reflect changes made to the infusion map, thusassisting the clinicians with their record-keeping requirements.Further, the present system aids clinicians in verifying the infusionsetup before administering a drug to a patient, thus helping to reduceerrors and save time.

In a first aspect, a patient information software system includes amemory storing at least infusion mapping instructions, and a processorthat executes the stored instructions. When the processor executes theinfusion mapping instructions, the infusion map system performs adisplaying function that displays at least a portion of an electronicmedical record associated with a patient, and a diagramming functionthat receives the electronic medical record and generates an infusionmap showing all intravenous drugs being administered to the patient. Foreach of the drugs, the infusion map further illustrates a route ofadministration for the drug. An order administering function performedby the system allows a user to alter the infusion map, and a recordupdating function of annotating the electronic medical record tocorrespond to the altered infusion map.

In another aspect, an infusion mapping process includes retrieving anddisplaying at least a portion of an electronic medical record associatedwith a patient, and generating an infusion map schematically showing allintravenous drugs being administered to the patient based on theretrieved electronic medical record. For each of the drugs, theschematic diagram illustrates a route of administration for the drug.The process further includes receiving a new order that alters theinfusion map, and updating the electronic medical record to correspondto the altered infusion map.

In still another aspect, a hospital information system includes anelectronic medical record server maintaining a plurality of patientelectronic medical records, and an infusion mapping device incommunication with the electronic medical record server. The infusionmapping device performs operations including retrieving at least aportion of one or more of the plurality of patient electronic medicalrecords, including a portion specifying intravenous drugs beingadministered to the patient and hospital equipment associated with theadministration of the drugs. For each of the one or more retrievedmedical records, the infusion mapping device displays an infusion mapthat schematically represents the portion of the medical recordspecifying intravenous drugs being administered and associated hospitalequipment. The device modifies the infusion map and updates theelectronic medical record based on the modified infusion map. Finally,the device saves the updated electronic medical record to the electronicmedical record server.

DETAILED DESCRIPTION

A patient information software system with infusion map is generallydesignated 10. The system 10 includes a computerized device 12, havingat least a memory 14, a processor 16, an input device 18, a networkcommunication interface 20, a display 22, and a power source (notshown). The memory 14 is preferably a non-transitory computer-readablerecording medium, such as a read only memory (ROM), random access memory(RAM), hard disk, non-volatile flash memory or other electronicallyerasable programmable read-only memories (EEPROMs), or optical ormagneto-optical memory storage medium. The memory 14 stores instructionsthat, when executed, perform the infusion mapping. The computerizeddevice 12 also includes the processor 16, which may be, for example, amicroprocessor or other central processing unit capable of executing theinstructions stored in the memory 14. The display 22 is a device such asa liquid crystal display, cathode ray tube, plasma display, or otherdevice capable of outputting data from the memory 14 and processor 16 ina way that is easily discernible by a user.

The network communication interface 20 allows the device 12 to connectto a network 24, such as a local area network (LAN), wide area network(WAN), and/or the Internet. The interface 20 connects to the network 24via a wired connection using, for example, the Institute of Electricaland Electronics Engineers (IEEE) 802.3 standard, or a wirelessconnection using standards such as IEEE 802.11a/b/g/n/ac, or any newlydeveloped standards that supersede these. The network interface 20 mayalso connect to one or more cellular data networks using standards suchand protocols as Long Term Evolution (LTE), Worldwide Interoperabilityfor Microwave Access (WiMAX), Global System for Mobile Communications(GSM), Code Division Multiple Access (CDMA) standards such as cdmaOneand CDMA2000, High Speed Packet Access (HSPA), Evolved HSPA (HSPA+),General Packet Radio Services (GPRS), and the like.

The computerized device 12 may take many forms, including a laptop ordesktop computer, a client computer integrated with a hospitalinformation system to allow for access at multiple locations (e.g.,pharmacy, nursing station, emergency department, diagnostic laboratory,and physician offices), a portable device such as a tablet, smartphone,personal digital assistant, or computer on wheels. Additionally, thecomputerized device may be integrated into bedside equipment such asinfusion pumps and/or patient monitors.

The memory 14 on the system 10 stores a patient list that includes aplurality of records listing each current patient, together with patientID information (ID number, date of birth, room number within thehospital, etc.), an infusion map, a list of pending activities relatedto the patient's infusion system, a list of past activities related tothe infusion system, and optionally a list of personnel authorized toview the patient's record. The patient list is preferably maintained ina central storage location accessible by all users of the infusionmapping system.

Each infusion map stores a list of drugs prescribed and/or beingadministered intravenously to a patient. One convenient method tomaintain this information is to integrate the system with theinstitution's Computerized Prescription Order Entry (CPOE) system, orother similar institution system, typically centralized in the hospitalpharmacy. Preferably each drug is stored in combination with at least adosage (concentration) of the drug, a volume of liquid in which the drugis diffused, a rate at which the fluid is being administered to thepatient, a specific pump (if any) used to facilitate the administration,a catheter port at which the drug is entering the patient's bloodstream,and an indication of what tubing connects the drug container to thecatheter. One of skill in the art will recognize that more or differentinformation may be stored as part of the infusion map without departingfrom the scope of this invention.

When a user interacts with the system 10 through a computerized device,he will be provided with a login prompt, requiring that the user provideauthentication credentials for the system. Such credentials may include,but are not limited to a unique username, password, and/or biometricidentification such as a fingerprint, voice sample, facial image or thelike. The system 10 will verify the provided login credentials and oncethe system has verified the user, the system displays a user name onscreen so that the user can easily verify that he or she is logged incorrectly, and can easily distinguish his or her device from othersimilar devices. The system 10 also uses this username when documentingdata input and actions taken.

Once the user logs into the system 10, the system presents a patientlist 26, as shown in FIG. 2. Alternatively, the user may be presentedwith a triage list of required actions corresponding to the patientworkload in place of or in addition to the patient list. To present thepatient list 26, the system 10 retrieves a list of patient names fromthe patient table, and displays a list of current patients, as shown inFIG. 2. If the patient table restricts access of the patient records toparticular users, the system compares the user ID of the logged-in userto the list or personnel authorized to view the patient record stored inthe patient table, and displays only those patient names correspondingto records the logged-in user is authorized to view. Additionally, thepatient list 26 preferably includes a notification icon 28 indicatingthat some action is required for a patient. In the example shown in FIG.2, the exclamation point icon indicates that there is an action requiredfor patient “John Doe.”

The user then selects a patient from among the list of patientsdisplayed. For example, the user may select “John Doe” from the patientlist 26. As shown in FIG. 3, when a patient is selected, infusion statusof the selected patient is retrieved from the patient table anddisplayed to the user in an easily-readable manner. The displayedinfusion status includes patient identification information 30, a listof all pending actions required for the patient 32, a list of allactions previously recorded for that patient 34, and a link 36 to viewthe infusion map associated with the patient.

As shown in FIG. 4, when user selects the link 36 to the patientinfusion map, the system retrieves the stored infusion map and builds agraphical representation of the map 38, which schematically illustratesthe various drugs currently being administered intravenously to thepatient, to display to the user. The infusion map 38 preferably showseach of the infusion drugs connected to the patient, together with agraphical representation of several pieces of information related toeach drug. In particular, each drug is typically labeled with its name,concentration, volume, and/or amount; a remaining time until that drugis completely infused; a label indicating the specific pump providingthe infusion (if any); the rate at which the pump is set; and the siteon the patient body to which the drug is connected. As an example, FIG.4 shows that John Doe is receiving Phenylephrine, in the amount of 40mg/250 ml; the remaining time before the Phenylephrine is completelyinfused is 3 hours and 5 minutes; the drug is being infused by asingle-channel large volume infusion pump set to a rate of 37 ml perhour, and is connected to a peripherally inserted central catheter(PICC) on the patient's right side. As can be seen in FIG. 4, each drugis similarly labeled.

The system 10 stores and can display additional information regardingeach of the elements shown on the infusion map. For example, when thePICC is selected, additional information 40 related to that site isdisplayed, as shown in FIG. 5. The displayed information includes a listof drugs that are connected to the catheter, an infusion rate for eachof the drugs, and a total infusion rate for the catheter. Theinformation also includes data relating to when the catheter wasinserted and when the catheter should be changed according tobest-practice guidelines or any guidelines specified by the hospital.Closing the additional information panel returns the user to theinfusion map display.

FIGS. 6-10 illustrate one of the various medication delivery workflowsthe system is capable of facilitating. As shown in FIG. 6, the patienthas a pending action item in list 32, indicating that the physicianand/or pharmacist has repeated an order for that patient. When a userselects a pending action to repeat an order, the system displays atleast a portion of the patient infusion map 38 containing the drugspecified in the order, as shown in FIG. 7. Additionally, orderinformation 42 related to the repeat order is shown. The information 42preferably includes an issuing physician, administration informationincluding amount of drug, amount of fluid, and infusion rate, andcompatibility information indicating whether or not the order iscompatible with the existing infusion map. Those skilled in the art willrecognize that different and/or additional information may be providedwithout departing from the scope of this invention.

To provide the compatibility information, the system 10 performs a drugcompatibility check regarding at least four aspects of drugcompatibility. First, the system 10 checks to determine compatibilitybetween the drug and the patient. Specifically, the system determines ifthe patient has any allergies noted in his medical record that would berelevant to the drug to be administered. Additionally, the system 10checks for any physical incompatibilities (e.g., precipitationinteractions) between drugs prescribed to the patient. Finally, thesystem 10 includes a mass flow balance model to check for errors in theflow of the drugs into the patient's system. Mass flow balance errorsare generally caused by an incorrect placement of a drug within apatient's infusion system, an unexpected or overlooked interactionbetween multiple infusion pumps, or other issues with the physicalequipment used to administer the drugs. Such errors include, forexample, an inadvertent bolus (an unintended increase in flow rate,causing a sudden increase in the drug concentration in a patient's bloodstream) or an inadvertent lag (unintended delay in administration ordecreased flow rate of a drug). The results of this compatibility checkmake up the compatibility information provided to the user.

The system 10 also highlights 44 a recommended configuration for theorder. Recommendations may be made by, for example, the issuingphysician or a pharmacist. As shown in FIG. 7, the system 10 suggestsreplacing the existing insulin infusion bag with a new bag. The system10 then prompts the user to either accept the suggested configurationand administer the drug 46, modify the suggested configuration 48, orcancel 50. In response to user indication that the configuration isaccepted 46, the system then prompts the user to confirm that the orderhas been administered 52, as shown in FIG. 8.

User confirmation preferably includes a simple click of a confirmationbutton 52 presented to the user, as shown in FIG. 8. Alternatively, orin addition to this confirmation, the user may be required confirm thedosage administration in other ways. For example, the user may berequired to scan a barcode corresponding to the administered drug. Thishelps to provide additional verification that the order was administeredcorrectly. Once the user indicates that the order was successfullyadministered, the system 10 displays a confirmation dialog box 54indicating that the repeat order was successfully administered, as shownin FIG. 9. Additionally, as noted in the confirmation dialog box 54shown in FIG. 9, when an action is successfully administered, the system10 automatically annotates the patient's electronic medical recordindicating the time the order was administered and the user whoadministered the order. Once the user clicks OK as shown in FIG. 9, thesystem 10 returns to the patient infusion status screen as shown in FIG.10. The screen shows the updated patient history 34 and removes thepending action item.

The system 10 also allows for handing of new orders, as shown in FIGS.11-15. Preferably, the infusion system provides real-time updatesregarding incoming orders for a patient under the user's supervision. Asshown in FIG. 11, when a new order is received for patient John Doe, anotification 56 is displayed to the user. The user is provided withoptions to dismiss 58 the notification or to open 60 the patient profilefor John Doe.

When the user selects “Open” 60 from the new order notification, thesystem preferably opens the order. FIG. 12 shows the new order screen.As discussed above, the screen includes order information 42 regardingthe physician who issued the order, the ordered drug (e.g., number ofunits of the ordered drug, volume of liquid to be infused, and infusionrate), and compatibility check information indicating that the drug asordered is compatible with the existing patient infusion map. The system10 also displays at least a portion of the patient infusion map 38, anda highlighted recommended configuration 44 for administration of theordered drug. Again, the user is presented with options to accept thesuggested configuration and administer the ordered drug 46, modify theconfiguration 48, or cancel 50. When the user accepts the configuration46, the infusion map 38 is updated to include the recommendedconfiguration as shown in FIG. 13. The system then prompts the user toconfirm that the order has been administered 52. The user then receivesa notification dialog box 54 indicating that the dose has beensuccessfully administered, as shown in FIG. 14. The system 10 alsoupdates the patient's electronic medical record to indicate the time atwhich the order was administered and the user that administered theorder, as indicated by the notification dialog box 54 present in FIG.14. FIG. 15 shows the updated infusion status screen for patient JohnDoe, reflecting the updated history 34 in the patient's electronicmedical record.

As shown in FIGS. 16-25, the system 10 also allows for additionalconfiguration options when a new order is received. When the userselects another patient from the user list, the infusion status screencorresponding to the patient is displayed, as shown in FIG. 16. Theinfusion status screen lists a pending action 32 for a new order. Whenthe user selects the pending action 32, the system displays a screenshowing the infusion map and the new order information.

As shown in FIG. 17, the new order information 42 includes informationregarding the physician issuing the order, the drug to be administered,the volume of fluid to be infused, and the infusion rate. However, noconfiguration has been suggested by the physician or pharmacist foradministration of the drug. Accordingly, the user is presented withoptions to retrieve configurations suggested by the system 62, manuallyconfigure the infusion 64, or to configure the drug infusion using abarcode scanner 66.

The system 10 is capable of suggesting one or more configurations forthe new order when the user selects item 62. The system 10 uses acompatibility check based on the new order information 42 and theexisting infusion map 38 to determine possible ways of connecting thenewly ordered drug that are compatible with the existing infusion map,and then suggests one or more of the compatible configurations to theuser.

Alternatively, the user may manually configure the setup by selectingitem 64. When the user selects a manual configuration, the system 10first prompts the user to select which catheter or access point theinfusion will be connected to at 68. As shown in FIG. 18, candidateaccess points, including existing catheters and access points, arehighlighted 70 on the infusion map 38 to aid the user in selecting apoint. Alternatively, the user may select a new catheter 72. Next, asshown in FIG. 19, the user is provided with a list 74 of extension setsfor use with the drug. Again, candidate locations 70 are highlighted onthe infusion map 38, showing where the extension set can be placed.Similarly, FIG. 20 shows that the user is presented with a list 76 ofpossible tubing sets and candidate locations 70 within the infusion map38, and FIG. 21 shows that the user is provided with a list 78 ofpossible infusion pumps for use with the drug, and highlighted locations70 where the pump can be positioned. For each of the lists 74, 76, 78,the system 10 provides a list of appropriate equipment options, togetherwith a description and representative image to allow for easy selectionby the user. The system 10 preferably displays only the equipmentavailable in a particular hospital or only the equipment available to aparticular ward of that hospital. Once the user has selected aconfiguration for the drug, the system 10 preferably verifies that theconfiguration is compatible with the existing infusion map 38 using thecompatibility checks described above, shows the infusion map 38 with thenewly configured portion highlighted 80, and prompts the user to acceptthe verified configuration 82 or modify the configuration 84, as shownin FIG. 22. The system 10 then displays an updated infusion map 38 andprompts the user to confirm that the dose has been administered 86 asshown in FIG. 23. As shown in FIG. 24, the system confirms that theorder has been administered via a confirmation dialog box 88 and updatesthe patient chart with the time and user administering the order. FIG.25 shows that the infusion status screen for the patient is updated toinclude the new order in the history list 34.

Referring now to FIGS. 26-30, the system 10 also allows for orders to bediscontinued. A pending action to discontinue an order for patient JohnDoe is shown in action list 32 on the patient infusion status screen,shown in FIG. 26. When the user selects the pending action, the infusionmap 38 is shown, and the system highlights the portion of the map 90affected by the discontinued order. Additionally, order information 42is shown indicating the physician who issued the order and order text.In the example shown in FIG. 27, the order text reads “DiscontinueVancomycin 1 g/250 mL.” Additionally, as with other orders discussedabove, the order information 42 preferably includes compatibilityinformation indicating that the order is compatible with the presentinfusion map. The user is prompted to accept the new configuration 92and discontinue administration of the drug as indicated in the ordertext.

As shown in FIG. 28, the system 10 then prompts the user to confirm 94that the dose has been discontinued. Once the user confirms that thedose has been discontinued, the system updates the patient medicalrecord to indicate the time at which the physician order was carried outand the user responsible for carrying out the order, and indicates thatthe discontinuation order was successfully carried out through aconfirmation dialog box 96 presented to the user, as shown in FIG. 29.The patient infusion status screen is updated so that the history list34 includes the current medical record information, as shown in FIG. 30.

Preferably, each item of hospital equipment and each drug containerincludes a unique identification code 98 registered in a databaseaccessible by the infusion mapping system 10. Here, an identificationcode 98 may be any machine-readable representation of data, includingvisual representations such as traditional parallel-line barcodes, QRcodes, or other known systems. Alternatively, the identification code 98may be stored and read via electronic means, such as RFID tags. As shownin FIGS. 31-42, the system 10 also preferably allows a user to configurea portion of an infusion map 38 based on scanning the one or moreidentification codes 98 corresponding to the drug container(s) andequipment used to administer the order. Additionally, both the patientand user possess also unique identification codes so that the patientand user can also be identified by the system.

FIG. 31 shows that a pending action for a new order appears in the neworder list 32 on the patient infusion status screen. In this case, thepatient is a new patient with no existing infusion configuration. Asshown in FIG. 32, no configuration is specified for the new order.Accordingly, the system 10 displays order information 32 associated withthe new order and prompts the user with several options forconfiguration, including a suggested configuration 62, includingsystem-suggested configurations and/or a pharmacist- orphysician-specified configuration, manual configuration 64 by a nurseusing a pick-list selection as described previously, or configurationusing a barcode scanner 66. When the user selects “configure withbarcode scanner” 66, the system prompts the user to scan barcodesattached to the appropriate hospital equipment using the input device18, which is preferably any known barcode scanner input device. Asnon-limiting examples, the input device 18 may be a camera integratedinto a laptop computer, personal digital assistant, tablet computer, orsmartphone, or a separate scanning device. As each barcode is scanned,the corresponding equipment appears in the infusion map 38, and thesystem 10 identifies the scanned equipment, prompts the user to verifythat the correct equipment has been scanned 100, and prompts the user toscan additional equipment 102, as shown in FIGS. 34-38. While theexample illustrated uses barcodes, any known identification code (e.g.,QR codes, RFID chips) may be used without departing from the scope ofthe present invention, as discussed above. Once a complete configurationhas been scanned, the system verifies that the configuration iscompatible, and prompts the user to accept the configuration 104, whiledisplaying the infusion map 38 with the newly-added equipmenthighlighted 106, as shown in FIG. 39. The system then prompts the userto confirm that the dose has been administered 108 as shown in FIG. 40.The patient record is updated to include the time that the order wascarried out and the user name of the person who administered the order.This information is presented to the user in a confirmation dialog box110, as shown in FIG. 41. Finally, as shown in FIG. 42, the patientinfusion status screen is updated to show that the order wassuccessfully entered into the patient's chart in the history list 34.

As shown in FIGS. 43-46, the system also provides training andinstruction for use information related to the equipment used toadminister intravenous drugs. Preferably, multiple training andinstruction items are available in a plurality of formats, including,for example, videos, instruction manuals, and the like. The items may bestored locally on the user's device (e.g., in the memory of a user'stablet, smartphone, etc.), centrally on a server accessible by allsystem devices (e.g., a hospital data server), or remotely, such thatthe training and instruction items are available via the Internet. Asshown in FIG. 43, the system 10 provides the user with a menu 112showing a selection of training and instructional use content. Inresponse to a user selecting an item of video content, the systemretrieves the selected video via a known method (e.g., playback frommemory, progressive download, streaming, etc.) and begins playback, asshown in FIG. 44. When the video finishes, or in response to a userinteraction, the system returns to the training and instruction menu, asshown in FIG. 45. FIG. 46 shows an example of a text-based instructionitem. Text based items may be, for example scanned documentationprovided by the equipment manufacturer, and are preferably searchabledocuments.

Additionally, the infusion map system 10 optionally includes moreadvanced medical record functionality, including notation ofnon-intravenously administered drugs, notation of laboratory test ordersand test results, and additional physician orders and actions taken. Thesystem 10 further optionally includes more advanced patient chartingfeatures.

Further, the system 10 is optionally integrated with other medicalinformation systems present at the medical facility including, but notlimited to, inventory management systems and billing systems. Thisintegration advantageously increases accuracy of inventory and billing,while simultaneously reducing duplicative work of noting drugs providedfor inventory and billing purposes by hospital staff and health careproviders.

Still further, the system optionally includes “personal nursingassistant” (PNA) functionality, planning a nursing schedule based onassigned patients and patient orders. This desirably ensures that nursesare provided with a manageable schedule that allows them adequate timeto see to patient needs, while also reducing scheduling time forhospital administration. This functionality preferably includes smarttriage functionality, arranging orders for a nurse according to multiplefactors such as patient condition, medication criticality, and othercompeting orders.

The system 10 also may be integrated with patient monitoring andnotification systems. This integration provides the user with a triageaction item when a notification such as an equipment alarm is received.
